ICNIRP recommends reference values for movements in magnetic fringe fields of MRI systems. Several probes have been presented using custom interfaces to record data. To open this field of research to a wider public a Raspberry Pi® based magnetic field monitoring system was built. A probe consisting of both three Hall sensors and induction coils was used. All channels were converted into frequency via voltage-to-frequency-converters. Data was stored internally via python. Measurements were performed on a 7T small-animal MRI at the hand of MR-workers. Reference values were exceeded at the hand. No transient effects like vertigo or nausea were noticed.
